Abstract
The disclosure generally describes methods, software, and systems, including a method for caching information. A request for information is received at a staging layer. A determination is made whether the requested information already exists entirely in a cache. In response to determining that the requested information does not exist entirely in the cache, at least some of the requested information from the underlying database layer is retrieved. A completeness level to which the requested information exists in the cache is determined. In response to determining that the requested information exists partially in the cache, cache-nonresident information is retrieved from the underlying database layer and merged with information in the cache. In response to determining that none of the requested information exists in the cache, the request is forwarded to the underlying database layer. The requested information is provided by the staging layer to a presentation layer.
